From the Back Cover
The main issue in the novel is the disappearance of Edwin Drood and the suspicion that he has been murdered. But as intriguing as this central plot are the startling innovations in Dicken's work and the troubled elements lurking within the novel: a dark opium underworld, the uneasy and violent fantasies of its inhabitants, the disquieting presence of old 'Princess Puffer', of the quiet cathedral town of Cloisterham from which people have to escape in order to save themselves--and, at the centre, the menacing figure of Jasper.
